Description
The cross reference of related application
The application requires in the current unsettled U.S. Patent application No.61/222 that is entitled as " Magnified Pointing Indicia Method " of submission on July 2nd, 2009,709 right of priority, and its content is herein incorporated by reference.
Technical field
The present invention relates to the amplification of computing machine display interface, and more specifically, relate to the wherein amplification of cue mark.
Background technology
Low eyesight individual often requires to amplify the computer screen interface and sees text and image clearly.Amplification system can be implemented in the third-party product that maybe can comprise feature rich in the operating system itself, such as those products of selling under the MAGIC brand of setting up in the Peshawar of Florida by the manufacturing of free scientific & technical corporation.
The deficiency of this area current state is the convergent-divergent cue mark from little dimension to big dimension, such as cursor or insertion symbol.For example, all mouse pointers have discrete minimum and public full-size.This minimum dimension is a plurality of system metrics that are used for mouse pointer.In general, this tolerance is 32 * 32 pixel square formations under the operating system under WINDOWS 7, VISTA and the XP trade mark that the Microsoft that comes from Washington Lei Mengde sells.Yet mouse pointer just occupies 16 * 16 upper left pixel square formations of adjustment in this tolerance usually.
When screen is amplified to high-gradely, during as 16 times, mouse pointer becomes pixelation and dispersion user notice.Various smoothing techniques can be employed to reduce pixelation, and still such processing consumes cpu cycle and still causes unfavorable result.
Another deficiency of prior art is the excessive amplification of cue mark.Because cue mark and whole graphic user interface as one man are exaggerated, so low vision user often is confined in the amplification that they can use.Therefore, cue mark becomes too big, so that they have obscured most of graphic user interface itself at high amplification stage (that is, above 16 times).
Summary of the invention
An embodiment of the invention provide the method for the cue mark of playing up amplification, comprise step: the transmitting-receiving of monitor application interface message; Intercepting is called current System pointer identifier (such as its handle); The set of the predefined shape vector of access stored; From said set, select predefined shape vector, selected shape vector is related with said System pointer identifier; Said shape vector is zoomed to an amplification stage; Rasterisation is the shape vector of convergent-divergent; And show the shape of rasterisation.Instead or in addition, passive intercepting is called current System pointer identifier, on one's own initiative to the said operating system of Set For Current poll of said operating system and resolve current System pointer identifier.
In order in can using the Windows of Microsoft environment of the present invention, to load mouse pointer, this LoadCursor API of application call (loading the cursor application programming interfaces) function:
If hInstance is empty, then IpCursorName comprises one the identifier of representing in the modular system cursor.These values comprise:
If hInstance is not a null value, then IpCursorName comprises the numerical value or the string identifier of the graph image that representative comprises in the resource of using.In one embodiment, the present invention creates dictionary able to programme, and its maps identifiers that will be returned by IpCursorName is to corresponding shape vector (it can be a plurality of forms, includes but not limited to CGM, SVG, ODG, EPS, PDF, SWF, WMF, EMF and XPS).Said dictionary and can realize through a plurality of programming techniques to the corresponding relation of said indicator identifier includes but not limited to ini file, XML file, csv file, database engine, web page server or the like.Said cursor sign to vector graphics can be to comprise multi-to-multi or man-to-man multiple relation.
LoadCursor returns to the numerical value handle cursor that has loaded.Foreground application is selected active cursor through calling this SetCursor function.This function obtains by one in the previous HCURSOR handle of creating of LoadCursor.Through these two functions of intercepting, can follow the tracks of the active cursor that application is just being used.Through intercepting SetForegroundWindow function, thereby can confirm that cursor that which is applied in the foreground and follows the tracks of which application is in system-level activity.
The ability that has improved level and smooth convergent-divergent mouse pointer or other graphical elements greatly through the image that uses based on vector is to create the image of the rasterisation that finally is used for last playing up (being plotted to screen) initial, buffer memory.Its reason is based on the shape and the key element of the image of vector and describes through formula rather than through bitmap.Current, all mouse pointers are described through bitmap.When amplifying, become " mottled " and " ladder-type stepped (stair-stepped) " that bitmap is intrinsic.Though and have the back convergent-divergent of bitmap that can using artificial " smoothly " convergent-divergent to handle, can not produce the image curling and sharp-pointed edge that has as the vector image generation of convergent-divergent.
The image file based on vector such as * .WMF file can be imported into and be associated with one or more System pointer handles or identifier.In order to raise the efficiency and responsiveness, through Cache can be under the situation of convergent-divergent and rasterisation shape once more storage or recall before with the shape of different amplification stage rasterisations.Usually on available memory device, carry out the storage of shape, said available memory device can include but not limited to magnetic hard drive, solid-state drive and/or RAM.
Alternate embodiments of the present invention comprises the steps: to set up the convergence point that is used for maximum cue mark amplification and sets up at user option desktop amplification stage, and amplification of synchro indicator mark and desktop amplification stage are up to reaching convergence point in view of the above.After this point, the desktop amplification stage can increase, and is static but the amplification of said cue mark keeps.When said desktop amplification stage drops to convergence point when following, then the amplification of said cue mark and desktop amplification stage are synchronous again.Being used for the said convergence point of amplification of the decoupling zero or the indicator-graphic user interface (GUI) that is coupled again can be based on several factor; Include but not limited to; The size of the indicator covering of available desk-top space, the amplification stage of said GUI, said cue mark itself, software application specific setting, incident setting are (promptly; Key in the unit of spreadsheet), keyboard and/or mouse event (that is, mouse roller moves) or the like.
In one embodiment of the invention, convergence point is in about 16 times of amplifications place.In another embodiment of the present invention, the cue mark of said maximum amplify to form as the about whole desktop area that calculates according to the giant-screen dimension 20 percent.For example the desktop of 680 * 480 pixels has the area of 307,200 squares of pixels.Be amplified to and adopt the indicator of 61,440 pixels can form 20 percent of whole desktop area, and therefore be counted as " higher limit " of indicator size.In another embodiment of the present invention, recently calculate convergence point based on the percentage of screen area according to less screen dimension.When in the out-of-proportion screen of major part, carrying out, through using less screen dimension, this convergency value has been realized rational behavior.For example, show that primary resolution is that the big dimension of the monitor of 1360 * 768 pixels is 2 times of less dimension nearly.Under similar these condition, preferably use less dimension will surpass any dimension of display never, only if the user clearly asks to guarantee convergency value.In above example, be actually 816 vertical pixels and surpass whole than the small screen dimension based on 60% convergency value of big dimension.In yet another embodiment of the present invention, the amplification of convergence point and maximum cue mark is that application is specific.For example, in spreadsheet is used, have the lower convergence point of necessary foundation, this cue mark can be less relatively to allow the user not having more easily to check spreadsheet cell under the situation about covering thus.Alternatively, require the user to select the test procedure of a plurality of option answers possibly have higher convergence point.Using specific convergence can be selected and/or user definition according to the individual needs of low eyesight in advance.
An alternative embodiment of the invention provides at user option desktop amplification stage, and it is independent of the amplification stage of the cue mark of user's amount of money selection.In this embodiment of the present invention, the user calls mouse, keyboard and/or the order of other peripheral hardwares and revises the amplification stage of cue mark to be independent of the GUI amplification stage.For example, the rolling mouse roller can amplify or dwindle GUI when keeping by the one or more key on the lower keyboard, and the rolling mouse roller can only amplify and dwindle cue mark when keeping pressing different key.The order of first keystroke is GUI and cue mark amplification synchronously.The order of second keystroke can asynchronous GUI and cue mark amplification.
The present invention can be embodied in one or more computer-readable mediums with computer executable instructions; Said computer executable instructions is used to carry out the method for runs software program on computers; Computing machine is operated under operating system; This method comprises from the software program issuing command, comprising: discern current System pointer identifier from the application programming interfaces of operating system; The predefined shape vector set of access stored; From this set, select predefined set of vectors, selected set of vectors is associated with current System pointer identifier; Shape vector is zoomed to an amplification stage; Rasterisation is the shape vector of convergent-divergent; And show the shape of rasterisation.Instructions stored is carried out as being used on computer-readable medium, is different from execution above that and drives grade alternately to revise the operating system of screen output with display.Alternatively, computer-readable medium can comprise operating system, or it is upgraded to realize the function of novelty of the present invention.

Embodiment
Forward Fig. 1 now to, low vision user 10 via mouse 30 and keyboard 40 at monitor 20 drilling longitudinal views.Cue mark 50 is illustrated being used for illustrative purpose as arrow cursor, but also can be to insert symbol.Cursor is to represent mouse and its graph image that moves on the Cartesian coordinates plane.It can adopt multiple shape, includes but not limited to, be used to refer to arrow, hand, hourglass or I type text selecting device.On the other hand, inserting symbol is to be used for the flicker mark of input text.When low vision user 10 was keyed on keyboard 40, letter appeared at and inserts the symbol place, and this insertion symbol lattice that move forward.In order to check relative amplification stage, videotex 60 and display graphics 70 are provided in Fig. 1.
The display graphics 70 that Fig. 1 shows GUI, cue mark 50, videotex 60 and do not amplify.In Fig. 2, with 2 times of amplification stages at conceptive cue mark 50, videotex 60 and the display graphics 70 of showing.In Fig. 3, with 4 times of amplification stages at conceptive cue mark 50, videotex 60 and the display graphics 70 of showing.In Fig. 4, with 16 times of amplification stages at conceptive cue mark 50, videotex 60 and the display graphics 70 of showing.In this grade, cue mark 50 approximately covers 20 percent of GUI area.According to embodiments of the invention, the additional amplification decoupling zero of GUI and videotex 60 the first preamble of GUI and cue mark 50 amplify.When the amplification of videotex 60 continued to increase above 16 times, it is constant that the size of cue mark 50 keeps.
In Fig. 5, decoupling zero in the amplification of cue mark 50 and the amplification of GUI.GUI is amplified to 16 times and only cue mark 50 is amplified to 4 times.Low vision user 10 can be used keyboard 40, mouse 30, and perhaps it makes up the amplification between decoupling zero cue mark 50 and GUI.Other peripheral hardware and input system such as speech recognition system can be used to carry out this incident.Also can be automatically and accomplish this decoupling zero intelligently through the present invention.The predetermined threshold that for example, can detect the mouse dormant state increases or reduces cue mark 50 progressively and amplifies with (as requested).
Mouse dormant state with external data can be used to make intelligence and amplify decision.For example, if the combined mouse dormant state detects a large amount of texts on GUI, can suppose that then the user is just in read text.Under these circumstances, the cursor that highly amplifies only can make view as text fuzzy.Alternatively, mouse 30 moves after the dormant state of a period of time immediately can call progressively amplifying fast of cue mark 50, makes when low vision user is reused cue mark 50, can easily position it.Said progressively the amplification can be as animation effect is provided.In other cases, the shape vector of a plurality of gradual modifications can provide other animation effect, such as mobile, rotation, waveform or the like.When shape be based on vector, when size reaches amplification stage, rasterisation and high-speed cache, the quality of figure provides the substantial advantage that surpasses this area current state with the efficient of the image of buffer memory of circulating.
Yet an alternative embodiment of the invention comprises the uncertain mobile step that after mouse 30 dormant states of a period of time, on algorithm, detects mouse 30 through low vision user 10, and the difficulty of the position of cue mark 50 is found in its indication.Uncertain moving can include but not limited to quick moving while arriving and circular motion.In response to detecting uncertain moving, amplify cue mark 50 according to the present invention for the time predefined section, turn back to the amplification stage that it is selected in advance then.The advantage that this embodiment is superior to prior art is the uncertain dormant state that must follow scheduled time slot that moves; If because the user should be used for so mobile software application of calling, the mouse that then is perceived as " uncertain " moves and possibly deliberate.
Fig. 6 illustrates and is expressed as little (◆), normal (■), big (▲), the convergence map of four (4) the individual different indicator sizes of huge (*).Little indicator size value is 0.5x.Normal indicator size value is 1.0x.Big indicator size value is 2.0x.Huge indicator size value is 4.0x.When 1 times of GUI amplifying, little, normal, big and huge indicator size cover respectively the GUI area～0%, 3%, 5% and 10%.Along with the increase that GUI amplifies, the variation of indicator size can produce remarkable distinct user experiences.Yet under embodiments of the invention, these indicator sizes can be normalized to 16 times of GUI and amplified.When GUI when 1 times is amplified to 16 times, little indicator size increases more in fact with respect to huge indicator size.Also can select other amplification stage to restrain.
Go to Fig. 7, the present invention expects that indicator creation application is so that the user can create shape vector and they are distributed to indicator collection or each indicator.The indicator collection comprises indicator light target different graphic image collection, and it depends on the environment that shows them and changes.When selecting text to edit, cursor can become vertical bar (I type mark).When translation around document, vernier can show as hand-type.It is barrel-shaped that the graphics edition cursor can show as the form of a stroke or a combination of strokes, paintbrush shape and pigment according to function.When waiting for that operation is accomplished, " wait " image can appear, such as hourglass or clock.Other indication option comprises color, pattern and transparency of selecting filling and line or the like.Specific software application can be distributed shape.This can obtain focus and use suitable indicator collection and/or as expect that revising cursor accomplishes to confirm which application through checked operation system communication.Because present method allows quick, clean playing up clear and clearly image on any dimension, animation property indicator cursor is possible.Shape vector stylization and/or the change sequence on dimension can be buffered, movably performance of cursor when showing this sequence in view of the above with drawing.Mouse roller zooming parameter and hot key combination can be assigned to specific shape and set.For example, the roll mouse roller is to amplify or to dwindle the indicator light timestamp in different directions, and the user can keep pressing keyboard combination.
Fig. 8 shows the importing application that is used for any graphic file based on vector is distributed to specific indicator and/or indicator set.The vector file form can include but not limited to meta file (EMF) and the XML paper standard (XPS) that PS file layout (EPS), Portable Document format (PDF), little webpage format (SWF), Windows meta file (WMF), the Windows of CGM (CGM), scalable vector graphics (SVG), opened document figure (ODG), encapsulation strengthen.Another advantage of the present invention is that low vision user more has the vectoring technology that is pre-existing in a large number and gathers with the cue mark as any amplification stage.As a comparison, owing to the pixel of bit map picture cause grating images be difficult to keeping clear with increase size clearly simultaneously.
In Fig. 9, embodiments of the invention are shown as process 70.For calling 90, the indicator handle keeps watch on API information receiving and transmitting 80.Carry out cross-check 100 to shape vector database 110 so that the indicator handle calls 90 is complementary with the shape that in shape vector database 110, is pre-existing in.Shape vector database 110 is included in one or more shape vectors of storing in the storer.Database 110 can be file directory, such as the structured document of XML, full relevant database or the like.Shape vector database 110 calls 90 with the indicator handle and is associated with relevant vector image.For example, if the indicator handle calls 90 request pointing hand images, then cross-check 100 determines whether to exist the vector image that is used for the pointing hand image.If do not exist, then bit map looks like to be exaggerated with level and smooth.Yet,, this vector image is amplified to suitable amplification stage and is rasterized into bitmap then if vector image exists really.Shape vector 120 is retrieved, and zoom function 130 is used to produce the shape vector 140 that has amplified.Come vector image execution convergent-divergent with width through the length that increases or reduce image.Because accomplished convergent-divergent, so there is not the pixelation as seeing in the mapping convergent-divergent on the throne to vector image.Rasterization process 150 is applied to the vector graphics 140 that amplified to produce the shape 160 of rasterisation, and it is shown 170 then and is cue mark.
Figure 10 illustrates adaptation and calls 90 alternate embodiment of the present invention (shown in process 75) at the indicator handle that does not have correspondingly-shaped in the shape vector database 110.Under the situation of not making coupling, mapping cue mark 180 in acquiescence position is amplified to the position mapping cue mark 190 of expansion.Position mapping cue mark 190 to enlarging is used smoothing processing 200, and shows 170 then.In another embodiment of the present invention; In case do not find coupling to shape vector; Then the low vision user 10 related existing shape vectors of system prompt are created new shape vector or are imported the file based on vector, as the replacement to acquiescence position mapping cue mark 180.In yet another embodiment of the present invention, when in shape vector database 110, lacking correspondingly-shaped, will give tacit consent to shape vector and offer the indicator handle and call 90.
Figure 11 illustrates the periodic polling 220 of operating system 210 to obtain current cue mark setting.Be provided with in case retrieve these, then select relevant predefined shape vector to be set with the mark of institute poll.
In Figure 12, the alternative method of obtaining indicator shapes is included in the step of operating system 210 and 230 intercepting drvSetPointerShape values 240 of display device driving.DrvSetPointerShape value 240 is indexed the shape vector 110 that drvSetPointerShape value 240 is correlated with by cross-check 100 to understand fully whether to exist.Use the drvSetPointerShape240 value to be suitable for the ten five (15) individual predefine (non-discarded) the cursor type in Microsoft's Window API standard most.
